Roll stability control (RSC)
Volvo's Roll Stability Control (RSC) is a stabilitysystem designed to help minimize the risk of arollover in emergency maneuvers or if a skidshould occur.
RSC uses a gyroscopic sensor that registers theamount of change in the lateral angle at whichthe vehicle is leaning. Using this information, RSCcalculates the likelihood of a rollover. If there isan imminent risk of a rollover, the stability systemis activated, power to the engine is cut and thebrakes are applied to one or more of the wheelsuntil the vehicle regains stability.

Deactivating and putting CC in standby
mode
To temporarily deactivate and put Cruise Controlin standby mode:
Function buttons and symbols (generic illustration)
–Press the button (2).
>The set speed marker (4) and symbols willchange colors from WHITE to GRAY.
This indicates that CC is temporarily instandby mode and will not maintain a setspeed.
Standby mode due to action by the driver
CC is temporarily deactivated and put in standbymode if:
•the brakes are applied
•The gear selector is moved to N
•the vehicle is driven faster than the setspeed for more than 1 minute.
In these cases, the driver will have to regulate thevehicle's speed.
A temporary increase in speed, such as whenpassing another vehicle, does not affect the CCset speed. The vehicle will return to the set speedwhen the accelerator pedal is released.

Automatic standby mode
CC switches automatically to standby mode if:
•the wheels lose traction
•engine speed (rpm) is too high/low
•brake temperature is too high
•the vehicle's speed goes below approx.20 mph (30 km/h)
In these cases, the driver will have to regulate thevehicle's speed.
Reactivating CC from standby mode
To reactivate CC after it has temporarily been putin standby mode:
–Press the button (1).
>The set speed marker (4) will changecolor from GRAY to WHITE. The vehiclewill then return to the most recently setspeed.

Distance Alert*
Distance Alert is a function that alerts the driverif the time interval to the vehicle ahead is tooshort.
Distance Alert is active at speeds above approxi-mately 20 mph (30 km/h) and only reacts to avehicle ahead that is driving in the same direc-tion. No information is provided for vehicles driv-ing toward you, moving very slowly, or at a stand-still.
Warning light (generic illustration)
A warning light in the windshield glows steadily ifyour vehicle is closer to the one ahead than theset time interval.

NOTE
Strong sunlight, reflections, extreme light con-trasts, the use of sunglasses, or if the driver isnot looking straight ahead may make the vis-ual warning signal in the windshield difficult tosee.

NOTE
Distance Alert only monitors distance to thevehicle ahead while Adaptive Cruise Control isin standby mode or off.

WARNING
Distance Alert only indicates the distance tothe vehicle ahead. It does not affect thespeed of your vehicle.
Head-up-display *
Distance Alert symbol in the windshield (generic illustra-tion)
In vehicle is equipped with the head-up display*,the symbol in the windshield will only appear ifthe distance to the vehicle ahead is shorter thanthe preset value. However, the Show DriverSupport In Head-Up Display function has tobe activated in the Settings menu. See the article"Head-up display" for additional information.

NOTE
Strong sunlight, reflections, extreme light con-trasts, the use of sunglasses, or if the driver isnot looking straight ahead may make the vis-ual warning signal in the windshield difficult tosee.

Distance Alert* limitations
Distance Alert uses the same radar sensor asAdaptive Cruise Control* and has several limita-tions.

WARNING
•The radar sensor has a limited field ofvision. In some situations it may detect avehicle later than expected or not detectother vehicles at all.
•The radar sensor cannot cover all drivingsituations and traffic, weather and roadconditions.
•The driver is responsible for maintaining asafe distance and speed and must inter-vene if the various driver support systemsdo not maintain a suitable speed or suita-ble distance to the vehicle ahead.
•Maintenance of radar sensor componentsmay only be performed by a trained andqualified Volvo technician.
•Strong sunlight, reflections from the roadsurface, strong lighting contrasts or usingsunglasses may make the warning light inthe windshield difficult to see.
WARNING
•Poor weather or winding roads can affectthe radar sensor's capacity to detect vehi-cles ahead.
•A vehicle's size (e.g., a motorcycle) canalso affect the radar sensor's capacity todetect another vehicle. This may result inthe warning light illuminating at a shorterdistance than the one that has been setor not illuminating at all.
•High speeds may also result in the warn-ing light illuminating at a shorter distancethan the one that has been set due tolimitations in the radar sensor's range.
For additional information, see also the article"Radar sensor limitations."

Adaptive Cruise Control (ACC)*
ACC is an optional system designed to assistthe driver by maintaining a set speed or a settime interval to the vehicle ahead.
ACC helps provide more relaxed driving on longtrips on highways or other major roads in a rela-tively even flow of traffic.
The camera and radar sensor monitor the distance tothe vehicle ahead (generic illustration - certain detailsmay vary from model to model)
The driver sets that desired speed and time inter-val to the vehicle ahead. When the camera andradar sensor detects a slower moving vehicleahead, your vehicle's speed is automaticallyadapted. When there are no longer slower mov-ing vehicles ahead, your vehicle will accelerate toresume the set speed.
ACC is designed to follow a vehicle ahead in thesame lane and maintain a time interval to that
